The initial amount of fat cells (adipose tissue) in your body is determined by genetics. Usually the amount of fat cells you are conceived with are not enough to lead to obesity. It is during the third trimester, the first two years after birth, and again during the post puberty period that the predisposition to obesity takes place. The number of fat cells in your body can be increased by a high fat diet at these times. Once you acquire a large amount of fat cells they never go away. They enlarge when you store fat and they shrink when you reduce it.
Not all fat is unhealthy. Your body requires essential fat for insulation, metabolic function, and to protect your organs. For this reason your body can convert both protein and carbohydrates (sugar) into fat when needed. Unfortunately, your body cannot convert fat back into protein and carbohydrate (sugar). There are only two ways to loss fat: 1) you can have it surgically removed; and 2) you can reduce your calories and increase your activity level so you burn it as fuel.
Skeletal muscle is the second most biologically active tissue in your body next to your heart. The more muscle you have the easier it is to burn fat. This is why it is recommended that a person exercise when they diet. Exercise will spare the muscle tissue so that mostly fat is lost while dieting. If you are not dieting but eating correctly while exercising, muscle tissue will grow, and your proportion of fat will reduce. Aerobic exercise burns 4 times more calories than anaerobic exercise per unit of time. When dieting, Aerobic exercise reduces fat faster.
Fat and muscle weigh the same. Fat is less dense then muscle. Because of this, a pound of fat will be larger then a pound of muscle. Fat is made up of 22% water, 72% lipids (fat), and 6% protein. Muscle is composed of 70% water, 7% lipids (fat), and 22% protein. The high water content of muscle causes you to lose mostly muscle when dieting without exercise. There are 3500 calories in a pound of fat. There are 600 calories in a pound of muscle. An extra 500 calories a day will add a pound of fat a week to your body.
There are individual tendencies to store fat cells in
different areas of your body. This is an inherited
characteristic that cannot be altered. Women accumulate fat
mostly in the legs, arms, and hips. Men will gather fat in
the back, and abdominal area. There is no such thing as spot
removal of fat unless it is done surgically. When reducing, fat is mobilized out of the
fat cells all over your body, then carried by the blood
stream to your active cells, and burned for energy. This
means that your fat deposits itself into specific areas of your body when
you accumulate the fat, but reduces from all areas of your body
when you lose it. The areas with the largest deposits are
the last to show the benefits of a fat loss program. This
fact makes it psychologically difficult to continue
exercising when an external appearance of fat loss is your
primary motivation. At a minimum, it takes several months to
change appearance. Just be patient. The only way to speed
up the process is to follow a high quality, scientifically designed,
personal prescriptive workout plan. Only The BioFitness Institute
can create this kind of plan for you. There is no other way.
